Efficiency - LED emits PAR light, i.e., photo synthetically active radiation, which offers greater efficiency and better results. When these lights are used for growing plants, they accelerate the growth because the wavelength of light that is emitted through them is exactly what the plants need. Plants have a specific requirement of wavelengths for conducting the process of photosynthesis.

The traditional white light bulbs will not provide such wavelengths and thus hamper the growth. Not just that, the incandescent lamps and fluorescent lamps will interfere with the growth of plants. Incandescent lamps produce more than 80% heat when lighted and thus emit heat instead of light. This kind of heat can be harmful for the plants. LED Low Bay Light flowering grow lights will produce light in the right frequency and wavelength. Moreover, the spectrum of red and blue light can be balanced for optimal results.

Beam angle: Do you know the beam angle of the bulb you are replacing? The beam angle of a bulb is measured as the angle between the two directions opposed to each other where the luminous intensity is 50% of the maximum luminous intensity. In simpler terms, the beam angle gives one a sense of how wide the beam spreads out when emitted from the bulb and can range from a narrow spotlight to a very wide floodlight.

A PAR LED spotlight will typically have a beam angle of twenty degrees or less while a PAR LED floodlight can range from the low twenty degree range all the way to forty-five degrees or more. It's almost a guarantee that you'll be dissatisfied with your purchase if, for example, you mistakenly buy a PAR LED spotlight when replacing a halogen PAR floodlight. Note: it can be difficult to find the beam angle on the bulb or packaging, but a quick search for the bulb model number on the manufacturer's website will usually lead to this information.
